1 barnacles
In recent years, barnacles are expanding, and many marine creatures have been tossed by them.
In 20 10, a huge turtle climbed the beach on the north side of Little Ryukyu Island in Taiwan Province Province. The turtle's entire shell and head are covered with countless barnacles, so it can only be judged from its shape that it is still a turtle.
Barnacles' bodies are wrapped in lime, and they hit the turtle shells one by one like patches. Some barnacles are piled together, while others are mixed together in disorder. If you have intensive phobia, you can't even look it in the eye. Tortured by barnacles, the tortoise was black and blue, lost appetite and soon died.
02, the harm of barnacles
1, increasing ship resistance and consuming fuel.
Due to the attachment of barnacles. The roughness of the part below the waterline of the ship increases, the resistance of the ship increases when sailing, and the self-weight of the ship increases, which leads to the decrease of the sailing speed of the ship and the increase of fuel consumption.
2, increase the weight and weaken the ability to resist risks.
If barnacles are attached to offshore oil platforms and building facilities, the self-weight of these facilities will increase, their external loads will increase, their ability to resist wind and waves will weaken, and they will easily tilt and collapse. At the same time, due to the increase of self-weight, the center of gravity of platforms and buildings has been improved, and the danger has increased when tsunami, earthquake and storm surge come.
3, affecting the comprehensive utilization of seawater resources.
Barnacle attachment will block the water supply and drainage pipelines of oil platforms and power plants cooled by seawater, which will affect the cooling effect of seawater. Even cause accident risk. Seawater desalination will lead to poor water inlet pipeline and reduce desalination effect.
